[Industrial applications]

 The present invention relates to a chemical fiber spinning filter mesh device, in which one or several filter meshes forming a relatively small and high-density ladder are inserted between multiple filter meshes. When the chemical raw material passing through the filter mesh passes through the filter mesh, the flow rate of the chemical raw material passing through the high density filter mesh is dispersed to the periphery to smooth the filtering effect and at the same time, the chemical raw material stays around the filter mesh. The feature is that it does not affect the quality of spinning by generating carbides to block the spinning holes.

[Prior art]

 Before the chemical fiber has not yet been formed into a spinning material, the liquid raw material is introduced into the charging tube by the pressure of the SURUKU metering pump in order to form a liquid state after undergoing a collective action. It flows into the filter mesh layer in the container, and the foreign matters are filtered by the multilayer filter mesh, then become fine raw fibers through the extruding of the spinning nozzle, and are further cooled and focused. Then, it becomes a low fiber that can be wound up and used for spinning.

As can be seen from the above work process, whether or not the raw material is pure depends on whether or not the pressure is evenly received on the entire surface of the spinning nozzle when the spinning is extruded. It has to do with the quality of the raw fiber you get.

Generally speaking, the commonly used filter mesh device has been gradually improved from the original two-layer structure to a multi-layer filter mesh structure, and the liquid raw material is charged into a charging tube by the pressure of a metering pump. When introduced into the container and then flowed into the container, relatively high pressure is exerted on the intermediate part between the container and the spinning nozzle, so that the raw material passing through this point is relatively even, and therefore relatively still. We can obtain good quality raw materials.

However, the raw material passing around the filter net receives uneven pressure when flowing, and therefore cannot receive the same pressure as the intermediate portion. Therefore, the raw material always stays around the filter mesh device to generate carbides, which easily clog the spinning hole in the spinning nozzle, so that not only the filtering effect does not reach the ideal value. In addition, the raw fiber extruded from the periphery of the spinning nozzle forms defective products such as fine fibers, scattered fibers, chopped fibers, crushed fibers, and hair fibers to improve the quality of the raw fiber. Have a great impact.

Therefore, in the past, efforts have been made to improve the number of layers of the filter network and the arrangement method so that the container can obtain a more uniform pressure and a better filtering effect. Not only was it effective, but rather the number of facilities could not be increased and improvements could not be made so much, and only the expense was spent.

[Problems to be solved by the device]

 In view of the above-mentioned drawbacks, the present applicant has devoted himself to research and development, accumulated his abundant specialized knowledge and technology, and after continuous testing and improvement, it is the first time to propose this chemical fiber spinning filter mesh device. I put it out. The present invention provides a chemical fiber spinning filter netting device, and its main purpose is to improve the filtering effect of spinning raw materials.

The present invention provides a chemical fiber spinning filter mesh device, which is even better for its built-up raw fiber so as to obtain an average pressure on each part of the filter device inside the container. The next object of the present invention is to improve quality and reduce defective products.

[0009]

[Means for Solving the Problems] The chemical fiber spinning filter mesh device according to the present invention has a multi-layered filter mesh in which one or several diameters are relatively small and the density is a fine ladder-like structure. The filter mesh is inserted into the filter mesh so that the raw material is evenly distributed over the entire surface of the filter mesh device by the action of the filter mesh, and the filtering effect of the raw material is further smoothed, and on the surface of the spinning nozzle. Not only has to obtain a very average pressure force, but also not to cause pressure unevenness in the raw material around the filter mesh device, and even if the filter mesh hole is used for a long time, it does not block the carbide, It is a very good quality polyester fiber spinning to even out the spinning substrate.

【Example】

 The special structure and its technical means and features used to achieve the above-mentioned designing purpose of the present invention in combination with the drawings will be described in detail as follows. Referring to the display of FIG. 1, it is a three-dimensional exploded view of the present invention, and the filter mesh device is assembled by connecting several filter nets 2 to a ring 3. Among them, the number of layers and the standard of the filter network 2 are different depending on the standard of the spinning machine (the technology of this section is not explained because it does not relate to the scope of the present invention). In the middle part, one or several high-density filter nets 4 arranged in the form of a fine ladder are provided. Diffuse and distribute.

FIG. 2 is a three-dimensional external view of the present invention, in which the filter netting device 1 is installed in the filter device 6 in the container 5, and the number of layers of the filter netting is different due to different spinning conditions. There is. As shown in FIG. 3, the container 5 encloses the charging tube 7, the filter device 6 and the spinning nozzle 8. When the raw material flows into the filter device 6 from the charging tube 7, the pressure and the flow rate of the raw material are almost constant. It concentrates in the middle part (as shown in Fig. 4), and the function around the filter netting device 1 becomes weaker there, or the pressure is relatively small, and the raw material easily stays around the filter netting and the carbide The phenomenon of blocking occurs.

However, if the filter netting device 1 of the present invention is used as a filtering facility, the raw material is blocked by the high density filter netting 4 in the filter netting device and diffused to the periphery, so that the raw material is evenly distributed over the entire filter netting device. And the pressure received in each part is evenly averaged, and the quality of the raw fiber 9 that is extruded from the spinning nozzle 8 at the bottom of the container 5 is very uniform, so that the fibers that are interrupted around it are It is a huge benefit for raw fiber molding without producing defective products such as scattered fibers, fine fibers, crushed fibers and hair fibers.

FIG. 5 is an illustration of a flow sheet for raw fiber molding. Raw fiber 9 molded from spinning nozzle 8 is processed in the order from cooling and focusing to winding before spinning. It will be the raw fiber you need. The present invention provides a good source of high quality and low defective raw fiber in the spinning industry, and helps improve the quality of the entire textile products.

[Effect of device]

 If the above is combined, the chemical fiber spinning filter mesh device of the present invention has a simple structure and is premised on the fact that the mechanical equipment of each chemical fiber factory is not modified and the production cost is not increased. In addition, the raw material has a better filtering effect, and at the same time, a better quality raw fiber can be obtained.
